His chest seems a little... blocky XDFace is a little derped and I could almost count the sides :SThe shirt seems longer than normal And the pants are very BOOF I also don't know what's happening with his left arm O.oIt seems to be missing a chunk >.>

Haha, the chunk missing is perspective based (yet I admit, a little extreme), he is leaning the right side of his body forward, obscuring some of the left side. This combined with the fact he's basically holding in his guts contributes to the "chunk effect" XDOh and as for the ENOURMOUS pants, I discovered that aswell as pants, male members of the Emestrian millitary actually wear skirts o.O [link]As far as the blockness of it goes, everything is geometric at 2AM ;D
